Hybrid vehicle has the advantages of saving energy and reducing emissions compared to conventional vehicles, BSG (Belt Driven Starter Generator) hybrid vehicles is getting more and more attention due to its little change to the original car and low cost. HESM(Hybrid Excitation Synchronous Machine) is used as BSG motor with its better torque properties than permanent magnet synchronous motor and excited synchronous motor, so it is of great significance to research HESM drive system.
